consideration of their parts being designed for quite other purposes. I never in my life chanced to see a peacock fly; and yet before, very long before I considered any aptitude in his form for the aerial life, I was struck with the extreme beauty which raises that bird above many of the best flying fowls in the world; though, for anything I saw, his way of living was much like that of the swine, which fed in the farm-yard along with him. The same may be said of cocks, hens, and the like; they are of the flying kind in figure; in their manner of moving not very different from men and beasts. To leave these foreign examples; if beauty in our own species was annexed to use, men would be much more lovely than women; and strength and agility would be considered as the only beauties. But to call strength by the name of beauty, to have but one denomination for the qualities of a Venus and Hercules, so totally different in almost all respects, is surely a strange confusion of ideas, or abuse of words. The cause of this confusion, I imagine, proceeds from our frequently perceiving the parts of the human and other animal bodies to be at once very beautiful, and very well adapted to their purposes; and we are deceived by a sophism, which makes us take that for a cause which is only a concomitant: this is the sophism of the fly; who imagined he raised a great dust, because he stood upon the chariot that really raised it. The stomach, the lungs, the liver, as well as other parts, are incomparably well adapted to their purposes; yet they are far from having any beauty. Again, many things are very beautiful, in which it is impossible to discern any idea of use. And I appeal to the first and most natural feelings of mankind, whether on beholding a beautiful eye, or a well-fashioned mouth, or a well-turned leg, any ideas of their being well fitted for seeing, eating, or running, ever present themselves. What idea of use is it that flowers excite, the most beautiful part of the vegetable world? It is true that the infinitely wise and good Creator has, of his bounty, frequently joined beauty to those things which he has made useful to us; but this does not prove that an idea of use and beauty are the same thing, or that they are any way dependent on each other.
